Planning and Design

Successful projects begin with detailed planning and design. Hoffman Construction surveys existing utilities to determine optimal routes for new installations, assesses soil conditions, and secures all necessary permits.

Site Preparation

We prepare the site by clearing vegetation, addressing storm drain needs, excavating trenches or pits, and ensuring access for equipment and crews.

Excavation

This crucial phase of underground utility construction involves carefully digging trenches or pits in alignment with design specifications. Depth, width, slope, soil type, space constraints, and existing infrastructure are all evaluated to ensure precision and project success.

Installation

Our team of experts ensures the precise installation of pipes, cables, and conduits for critical utilities such as water, electricity, gas, and storm drains, adhering to project specifications and industry standards.

Backfilling and Compaction

Trenches are carefully backfilled with soil and then compacted to ensure stability and prevent future settling.

Testing and Inspection

To ensure compliance with safety and regulatory standards, each utility installation is subjected to comprehensive testing and inspection, including pressure testing and detailed visual examinations.

Documentation

Comprehensive documentation is the final step, capturing every detail of the completed utility installation. This includes as-built drawings, material usage records, and all relevant permits and certifications, ensuring full transparency and compliance with industry standards.
